New whitepaper released: SAP High Availability with Tivoli System Automation for Multiplatforms

The Tivoli System Automation development team just released a whitepaper on SAP High Availability with Tivoli System Automation for Multiplatforms on AIX and Linux.

This paper describes an approach to creating a highly available SAP solution that covers all critial components. The IBM High Availability (HA) middleware solution (Tivoli System

Automation for Multiplatforms) provides this level of high availability.

High availability is a term used to describe systems that are continuously available that are up and running, performing the tasks they are dedicated to and are available to end users mostof the time.

This implies:• When failures occur, either caused by hardware or software, highly available systems must recover quickly.• Even on peak loads and a loss of availablility, the systems must perform appropriately and process transactions within a reasonable amount of time.

A highly available SAP installation will meet a recovery time objectives of a few minutes.

Tivoli System Automation for Multiplatforms is a high availability cluster solution and automation product that provides several monitoring mechanisms to detect system failures and a set of rules to initiate the correct action without any user intervention. The set of rules is called a policy, this policy describes the relationships between applications or resources. This policy and the monitoring mechanisms provide System Automation for Multiplatforms with extensive up-to-date information about the system landscape so that it can restart the resource on the current node or move the whole application to another cluster node.

When the database of your SAP system is IBM DB2 for Linux, UNIX, and Windows the cluster manager System Automation for Multiplatforms is already included. DB2 for LUW itself can be protected using System Automation for Multiplatforms.

To protect the SAP Central Services, System Automation for Multiplatforms will be deployed on the cluster nodes and will be configured to monitor the SAP Central Services.

The paper will detail why companies need HA solutions for SAP, and introduce degrees of availability. Furthermore, it describes which components of an SAP system should be protected, and highlight the available IBM solutions for SAP high availability.
